MORA-BARAJAS, M.A.  e  BANUELOS-SANCHEZ, P.. Harmonic Pollution Produced by Low Power Nonlinear Loads: Mathematical Model and Practical Cases. Ing. invest. y tecnol. [online]. 2010, vol.11, n.2, pp.189-198. ISSN 2594-0732.

Many household electrical appliances like televisions, video recorders and computers are sources of voltage and current harmonics, which increase power losses and contaminate the AC power line. These harmonics can cause serious problems in both, utilities and electrical equipments connected to the same AC line. This paper shows a mathematical analysis of harmonics content on the electrical current for a circuit representing a non linear residential load. A comparative harmonic distortion study produced by the residential loads on the electrical power lines, measured experimentally, is also shown.

Palavras-chave : Power factor; power losses; non-linear loads; low power; harmonic distortion; electrical energy quality.
